Outcome Measures

Primary Outcome Measures

Mood [Change from baseline the total mood disturbance after 90 minutes.]
The Spanish adaptation of the 30-item Short Form of the Profile of Mood States will be utilised. There are five questions situated under each mood factor of Anger, Fatigue, Vigour, Friendliness, Tension, and Depressed Mood, which will be rated on a five-point scale starting from 0 indicating "not at all" up to 4 indicating "a lot" to evaluate the current feelings. Higher scores on the vigour and friendliness subscale indicate more positive mood, and higher scores on the remaining subscales indicate more negative mood.

Secondary Outcome Measures

State stress [Change from baseline state stress after 90 minutes.]
The perceived stress will be assessed by the 100-mm Visual Analogue Scale, where endpoints are labelled as "None" and "As bad as it could be" from left to right. The scale will yield a single quantitative variable regarded as the state stress score, which is measured by the distance between the far-left end and the participant's mark on the line in millimetres. Lower scores indicate less stress at the moment.
State anxiety [Change from baseline state anxiety after 90 minutes.]
The 100-mm Visual Analogue Scale for state anxiety will be employed. The endpoints of the scale are labelled as "None" and "As bad as it could be" from left to right. The distance in millimetres between the far-left end and the participant's mark will be regarded as the state anxiety score. Lower scores indicate less anxiety at the moment.
